the theatres around here offer this cc device that you bring with you into the theatre. it's rather large / bulky and had the text displayed in a bright green. i would have to balance my viewing between looking down at the subtitles and up at the screen. i didn't find it too ideal.
in TO I could get a special pair of glasses that showed the subtitles right on the screen while not affecting anyone else watching the movie, I really enjoyed that.
